Peter Bright has summarised some of the post-fork discussions on the WebKit mailinglists. "Now that Google is going its own way and developing its rendering engine independently of the WebKit project, both sides of the split are starting the work of removing all the things they don't actually need. This is already causing some tensions among WebKit users and Web developers, as it could lead to the removal of technology that they use or technology that is in the process of being standardized. This is leading some to question whether Apple is willing or able to fill in the gaps that Google has left." There's a clear winner and loser here.

Well, the WebKit2 architecture was done by Apple and merged in and improved over time. That is work outside of the tree and later time-intensive fixing and maintainence that are not visible in such a diagram. Same for Google's massive 1GB test suite for Chrome/V8 which is probably a higher segment in there diagram color but got removed with Blink.

Save is only to say something changed. Two WebKit's. Now I am waiting for those that complained weeks ago, when Opera joined WebKit, that there are to less independent browser engine implementations to raise and praise this new situation. Seems they are all in holidays.
